The mindset of the civil service system design in Taiwan has been confined to a single-track rank-in-person system. That causes a dilemma of establishing a senior civil service between by internal promotion and by external recruitment. The new personnel system has strengthened the human-centered nature but at the expense of professionalization. These are not essential problems of a career-based system. The real problem is we have not seriously explored the possibilities of other civil service systems. This paper illuminates the Hong Kong's civil service system that was established in the colonial era. That system adopts a multiple-track rank-in-person system and a generalist-specialist grade division. This design facilitates rejuvenation of senior civil service and helps establish a human-centered professionalized grade system. The grade management helps realize the ideas of contemporary human resource and talent management. This case does not provide a state-of-the-art design, but it is well worth a reference for Taiwan.
